I have many lawns to renovate this coming season due to the widespread problems on bentgrasses and poa invaded lawns. Most of these lawns will be planted or sodded to TTTF and KYB. I am planning to use either one of the herbicides as a pre to avoid poa germ and obviously other grassy weeds during grow in. I would like anyone's feedback on precautions and rates when using these products. I have never used them as a pre. Thanks!
